Question

用3，5，6，7这四个数字计算出24，算式是什么?

Answer 1

计算的结果是24，
四个数中有3，则5,6,7三个数配出8即可，
则：3*（6-5+7）=24
四个数中有6，则3,5,7三个数配出4即可，
则：6*（5+7）/3=24

Answer 2

3*(6-(5-7))
3*((6-5)+7)
3*((6+7)-5)
3*(6+(7-5))
3*(7-(5-6))
3*((7-5)+6)
3*((7+6)-5)
3*(7+(6-5))
(5+7)/(3/6)
((5+7)/3)*6
((5+7)*6)/3
(5+7)*(6/3)
6/(3/(5+7))
(6/3)*(5+7)
6/(3/(7+5))
(6/3)*(7+5)
(6-(5-7))*3
((6-5)+7)*3
6*((5+7)/3)
(6*(5+7))/3
((6+7)-5)*3
(6+(7-5))*3
6*((7+5)/3)
(6*(7+5))/3
(7+5)/(3/6)
((7+5)/3)*6
(7-(5-6))*3
((7-5)+6)*3
((7+5)*6)/3
(7+5)*(6/3)
((7+6)-5)*3
(7+(6-5))*3

Answer 3

3*(6-(5-7))
3*((6-5)+7)
3*((6+7)-5)
3*(6+(7-5))
3*(7-(5-6))
3*((7-5)+6)
3*((7+6)-5)
3*(7+(6-5))
(5+7)/(3/6)
((5+7)/3)*6
((5+7)*6)/3
(5+7)*(6/3)
6/(3/(5+7))
(6/3)*(5+7)
6/(3/(7+5))
(6/3)*(7+5)
(6-(5-7))*3
((6-5)+7)*3
6*((5+7)/3)
(6*(5+7))/3
((6+7)-5)*3
(6+(7-5))*3
6*((7+5)/3)
(6*(7+5))/3
(7+5)/(3/6)
((7+5)/3)*6
(7-(5-6))*3
((7-5)+6)*3
((7+5)*6)/3
(7+5)*(6/3)
((7+6)-5)*3
(7+(6-5))*3

Answer 4

7-5=2，2+6=8,3x8=24 综合:3x（7-5+6）=24

Answer 5

3*(7+6-5)=3*8=24
(5+7)*(6/3)=12*2=24
